#6 An Flare To 3/8in Pipe

The #6 AN Flare To 3/8in Pipe fitting is a critical adapter for automotive fuel, coolant, and hydraulic systems where reliable connections are non-negotiable. Whether you're building a custom fuel system, upgrading your brake lines, or fabricating a power steering setup on your performance build, this adapter bridges the gap between AN flare connections and standard NPT pipe threads. Mechanics and fabricators rely on these adapters to create clean, leak-free transitions in high-pressure applications where factory routing won't work.

AEROQUIP's #6 AN Flare To 3/8in Pipe fitting features precision-engineered AN flare compatibility on one end and National Pipe Thread (NPT) on the other, ensuring compatibility with both modern AN hose assemblies and legacy pipe-threaded components. The flare design creates a metal-to-metal seal that withstands pressure spikes common in fuel injection systems, turbocharged setups, and high-flow cooling circuits. AEROQUIP's reputation in motorsports-grade hydraulics means this adapter meets stringent SAE standards and handles sustained pressure without weeping or failure, making it ideal for both street and track applications.

This adapter is essential for engine builders transitioning custom hose runs to existing threaded ports on radiators, water pumps, or fuel distribution blocks. Engine bay heat and vibration demand materials that won't corrode or loosen; AEROQUIP's construction handles thermal cycling and mechanical stress that plastic fittings cannot. Installation requires a simple wrench tightening—no special tools needed—making it a quick solution for plumbing modifications on LS swaps, fuel system upgrades, or brake line reconfiguration on modified vehicles.
